Prompt

We are building a web application using a neobrutalist visual aesthetic and need a complete, implementation-ready design system specification document. Please draft comprehensive design guidelines covering our core UI. Organize the output to include background goals, foundational visual tokens, component-level specifications (anatomy, variants, and interaction states), testable accessibility acceptance criteria, content tone standards, anti-patterns, and a QA checklist for code reviews.

Accessibility

WCAG 2.2 AA, keyboard-first interactions, visible focus states

Writing Tone

concise, confident, helpful

Rules: Do

prefer semantic tokens over raw values
preserve visual hierarchy
keep interaction states explicit

Rules: Don't

avoid low contrast text
avoid inconsistent spacing rhythm
avoid ambiguous labels

Expected Behavior

Follow the foundations first, then component consistency.
When uncertain, prioritize accessibility and clarity over novelty.
Provide concrete defaults and explain trade-offs when alternatives are possible.
Keep guidance opinionated, concise, and implementation-focused.
